@

Manage operations related to the current node.

<@

Receive current node name.

Datatype: MDI_CHAR
Quantity: MDI_NAME_LENGTH

The engine sends the driver a string that corresponds to the name of its current node.

Examples

Python

import mdi

# connect to the engine
mdi_engine = mdi.MDI_Accept_Communicator()

# send the "<@" command to the engine to get the current node
mdi.MDI_Send_Command("<@", mdi_engine) 

# receive the name of the current node
node_name = mdi.MDI_Recv(mdi.MDI_NAME_LENGTH, mdi.MDI_CHAR, mdi_engine)

C++

#include "mdi.h"

// connect to the engine
MDI_Comm mdi_engine = MDI_Accept_Communicator();

// create a buffer to hold the name of the current node
char* node_name = new char[MDI_NAME_LENGTH];

// send the "<@" command to the engine to get the current node
MDI_Send_Command("<@", mdi_engine);

// receive the name of the current node
MDI_Recv(node_name, MDI_NAME_LENGTH, MDI_CHAR, mdi_engine);

@

Go to the next node.

The engine proceeds to the next node. Typically not supported at the @DEFAULT node.

Examples

Python

import mdi

# connect to the engine
mdi_engine = mdi.MDI_Accept_Communicator()

# send the "@INIT_MD" command to the engine (so we are not at default node)
mdi.MDI_Send_Command("@INIT_MD", mdi_engine)

# send the engine to the next node.
mdi.MDI_Send_Command("@", mdi_engine)

C++

#include "mdi.h"

// connect to the engine
MDI_Comm mdi_engine = MDI_Accept_Communicator();

// send the "@INIT_MD" command to the engine (so we are not at default node)
MDI_Send_Command("@INIT_MD", mdi_engine);

// send the engine to the next node
MDI_Send_Command("@", mdi_engine);
